of parts when the :teeler is moved frontwardly by a working supply of filling ondetectingbeat; and s w Fig. 4 is a similar view showing the rela otion-of part-swhen the feeler is displaced laterally by the frontward pressure of a surface within the shuttle when filling is substantially exhausted.

The feeler mechanism as'shown is associated with filling replenishing mechanism, but sincethe: details thereof form no part of the present invention and are now well understood in the art,the replenishing mechanism is, not .shownand described.

usual in feeler mechanisms,.the shipper stand is provided with a laterally extending siipportlhaving a slot 2 for a-bracket 3 which imay'be adjustably secured in place by a suitable bolt 4:.

Adjustably mounted upon the bracket 3 is the feeler stand 5 secured in the desired position by a bolt 6 which passes through a slot 7 formed in the feelerstand.

Mounted upon the feeler stand for move ment towards and from the front of the loom is a slide which may be constituted, 'asshown, :by an upp'erplate 8 and anunder plate 9, the latter ofiwhichis mounted in a guideway 10 at. one side of the .ifeeler stand and held in sliding relation tojthe stand by an overlying clip 11 which iss'ecured to the feelerstand by a'screw12. Asshown, the slide maybe for med'of light sheetmetal, if desired, and bent at itsrfront portion to form the npper and lower plates 8 and9 respectively.

i" .The fe'elei 'stanclh has an upwardly pro- --jeoting'fiange l3 at its rear portion, and con- I V neetedl to the flange is a hook member 14: to nd novel features-thereof; v1llfbestbe made clear "fronithe fol-lowing] le'scription and the accompanying:,drawin gs which one end of a spring15 is secured, the oppositeendof thesprmg being connected to aalug 1'6 rising from the feeler slide,the ef- V fect ibeingthat the spring 15 normally tends to move the slide into its rearward position.

The feeler 17 has an ofiset pivotal connection with the slide and, as shown, the feeler comprises a 'rearwardly extending-arm 18 having filling engaging teeth '19 at its rear end and at its front end portion the feeleris provided with a laterally extending arm 20 which crosses to the opposite side of the feeler slide andis pivotally connected to the feeler slide at 21.

The laterally extending arm is provided with a toe 22 atits' free end and a stop 23,,0n

the laterally extending arm 20 serves to limit the swinging movementof'the feeler. about its offset pivotal connection with the slide, as indicated in F 1g. 4.

Associated wit 2a which is pivotally connectedito the feeler stand at 25 and has an upstanding flange .26

which is in the path of the toe 22 of thefeeler as the feeler is moved rearwardly into feelmg position, the result belng that as the feeler is moved rearwardly under the impulse of the spring 15, the toe 2 2 of the feeler arm will engage the upstandingflangei26 of the call plate, as indicated by dotted lines,

-Fig; 3, and cause the feeler to be turned about its pivotal connection with the feeler slide intoproper feeling position.

. The call plate 24 is extended frontwardly from its pivotal connection with the feeler stand at 25 and at its frontportion has secured to it a transmitter 27, whichQthrough a train .of'mechanism now well understood,

will initiate replenishment of filling when the feelerl detect s'substantial exhaustion of filling in theshuttle on a detecting beat.

- It'may be desirable at times to provide the call plate with a light spring to normally 7 4 maintain it in its normal position,}as indi-.

cated in F ig. 3, and such spring may, be-

coiled about the pivotal connection 25 of the call plate, asindicatedut 28.

As indicated more clearly in Figs. 1 andv 2, the call plate 24 is pivotally connected to the feeler stand at the under side thereof, in order that the call plate may have free swinging movement without interfering with other portions of the mechanism. i f l V] hen a working supply of'filling is present in the shuttle on a detecting beat, the toothed end portion'19 of the feeler'willlengage and sink into the filling, thereby normallypreventingside slipping movement of the feel er, and as the lay moves frontwardly the slide 8 will besimilarlymovedl As the lay moves frontwardly, the-pressure uponthe end 7 of the 'feeler becomes greater, and in case the feeler should side slip after ithas'b'ee'n moved frontwardly to a degree by the oncoming filling, it will be turned about its pivotal connection with the slide; but since the slide and feeler have both been moved frontwardly, the toe 22 of the feeler will not strike for" impinge upon the upstanding flange 26 of the h the feeler is a call plate call plate. and filling replenishment will not be called; Should the filling be substantially" exhausted on a detecting be'at,-however, the

feelerwill-partake ofits side slipping move- V 1 ment under the frontward pressure of the bobbin or filling carrier in the shuttle before itis moved frontwardly, with the result "that the toe 22 connected by thelateral arm 20 with the feeler, will bear upon. the upstanding flange 26 of the call plate and cause the latter cated in Fig, 2, whereupon ment willbe initiated. v

. As hereinbefore stated, the feel'er is mounted upon the feeler slide'forunrestricted piv otal movemennso that upon backward move ment of the lay after thefeeler has been laterally displaced, the call plate; will assume its normal position, as indicated in Fig, 3, and

actupon the toe 22 of the feeler to return it to its proper feeling position.
